Although more expensive, copper wire is far more safer and convenient. When inspecting your new home, consider the number of electrical outlets, particularly in your new kitchen. Are there enough light switches throughout the house?
Correct fuse or circuit breaker size:
Electric stove - 50 amps
Clothes dryer - 30 amps
Water heater - 30 amps
Washing machine - 20 amps
Dishwasher - 20 amps
Furnace - 15 amps
A circuit breaker has a tripping mechanism that opens a switch when current exceeds rated amperage. In may respects, a circuit breaker works like a switch of its own. When flow returns to normal, you have to reset it.
